Here's Ingraham's tweet mocking David Hogg:

2 days of advertiser boycotting later...

For some Twitter users, the writing is on the wall.

Former Fox News president Joe Peyronnin told me today the advertiser boycott "could be fatal" https://t.co/beBcgsU6fu

Huffpost reported that the list of companies boycotting Ingraham's program included:

Nutrish, the pet food line created by celebrity chef Rachael Ray, travel website TripAdvisor Inc, online home furnishings seller Wayfair Inc, the world's largest packaged food company, Nestle SA, online streaming service Hulu, travel website Expedia Group Inc and online personal shopping service Stitch Fix.

Ingraham tried to apologize to David after it became clear her advertisers were fleeing the program.

Any student should be proud of a 4.2 GPA —incl. @DavidHogg111. On reflection, in the spirit of Holy Week, I apologize for any upset or hurt my tweet caused him or any of the brave victims of Parkland. For the record, I believe my show was the first to feature David...(1/2)

... immediately after that horrific shooting and even noted how "poised" he was given the tragedy. As always, he’s welcome to return to the show anytime for a productive discussion. WATCH: https://t.co/5wcd00wWpd (2/2)

In an interview with CNN, Hogg chose not to accept Ingraham's apology.

I think it's great that corporate America is standing with me and the rest of my friends. When you come against any one of us -- whether it be me or anybody else -- you're coming against all of us.

I think it's important that we stand together as both corporate and civic America to take action against these people and show them that they cannot push us around, especially when all we're trying to do here is save lives. I think it's really disgusting, the fact that she basically tried promoting her show after apologizing to me.

Time will tell whether history will repeat itself. Ingraham's days on television could be numbered...

Both Bill O'Reilly and Sean Hannity took "vacations" as advertisers fled their programs
